Apia is both the largest town on the island of Upolu and the capital of Samoa. Despite its important function, this port has retained its small-town character. Most of Apia's attractions are located around the centre of the town at the harbour, including the clock-tower (the town's old landmark), the government building and the "Museum of Ancient and Recent Samoan History. Just five kilometres from the city centre is the 15 metre high natural water slide "Papaseea Sliding Rocks". The tiny village of Vailima is also well worth a visit. It is here that world-famous author Robert Louis Stevenson spent the last few years of his life. One of Stevenson's best- known novels is "Treasure Island".
